Best Answer: Pokemon has only ever been and will only ever be a game series released on Nintendo platforms.

Nintendo is a partial owner of The Pokemon Company.

There are many Pokemon games available for the 3DS family of systems. The cheapest way to get started would be to look for a 2DS (not the "new 2DS XL") which should cost about $70 - $80 for the system and usually comes with a game pre-loaded (look for a system that looks like a door stop wedge vs. a clam-shell system.

Then the Pokemon games usually cost about $40.

There is a new Pokemon game coming out this fall for the Nintendo Switch, but that is a much larger cost ($300 for the system and $60 for the game) and not really sure that I would get a Switch for one so young.
